How anntenas affect your radio range

The included antenna with the BaoFeng UV5R are quite bad. Almost anything would be better. You'd have to change to a dummy load to act worse.

Any antenna you select, it need not be anything specific to your radio transceiver. Whatever antenna appropriate for any bands you want to lock will be fine. The only thing with BaoFeng radios is they have a male connector (SMA) on the radio where allmost all other radios have a female connector. Male connectors are popular enough now you can find antennas with similar connector, or you can fi​​nd connector adapters.

Despite its quality, rubber antennas compromise size for efficiency. It is mostly true that the lower an antenna is built, the less competent it is. A normal whip will be a twenty-five percent wavelength, so around one-half a meter far for the 2 meter band. There exists designs with some degrees of shortening anywhere between that and a UV5R rubber antenna, so get the longest farseeing one that fit your tastes to maximize the range.

Almost all HT antennas can be bought for less than $100. You are able to purchase a 1/2 wave very high frequency Nagoya antenna from nearly all online markets for around $10. Best brands will be a brief more.

The dBi value means the forward gain of the antenna when it is compared to a abstract isotropic antenna (therefore the i in dBi) that beams all its power equally in all ways. To be of any use in your case, you'd need to acknowledge the dBi gain of the UV5R OEM antenna, they have traded away performance for size therefore whatsoever whip antenna is about assured to perform less spoiled.
